Engine/Transmission (1994 - 1998) Idle ajustment

[DWJoy]

I have a 96, auto. Idle is a little low. Is their a screw to ajust or how do you ajust? I can't see any ajust screw.

Yes there is an idle adjustment screw. If you look at the rear of the injection pump where the linkage is you will see it. Moving the linkage may help to bring it to your attention.

You need a 10 mm box end wrench. Find the lock nut and loosen it. Pull on the linkage with your left hand to relieve pressure on the adjustment screw so you can turn it with your fingers to do the adjustment. When you get it right tighten the lock nut.

Also, the idle adjustment bolt gets worn, and it make the adjustment a little bit unpredictable. You turn it a bit to raise it, and the idle goes up. You want just a little bit more, turn it some more and the idle drops again.



Don't get frustrated. You have a couple of choices.

Keep playing with it.

Remove the bolt and flatten the end of it with a file.

Replace the bolt.



I usually choose option 1 or 2 depending on how careful I feel like being.
